Question

For example:

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    this.cars = function() {
        this.value = start_value;
        this.count = start_value;
    };
}

Obviously the above dosent work but would appreciate the direction to take to have cars available as:
userObject.cars.value = 100000;

Cheers!

Answer 1

Remember that functions (and thus “object definitions”) can be nested (there is absolutely no requirement that this is nested, but having it nested here allows a closure over start_value):

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    function subObject () {
        this.value = start_value;
        this.count = start_value;
    }
    this.cars = new subObject();
}

However, I would likely opt for this (just create a new “plain” Object):

function userObject(start_value) {  
    this.name = start_value;
    this.address = start_value;
    this.cars = {
        value: start_value,
        count: start_value
    };
}

Happy coding.
